Ideal plate heat exchanger kit 173544

This Ideal plate heat exchanger kit is compatible with Esprit 2, Evo, Isar and Excel boilers and includes O-rings and screws for simple fitting. The heat exchanger transfers heat from a boiler's burner to water. A primary heat exchanger is found in all boilers, using heat from a burner to raise the temperature of the water in the system while a secondary heat exchanger is present only in combis and allows the heat to be transferred between closed systems.
